Book Description
This study provides information about over and undercrossings directed toward planners, designers and decision makers who are trying to best serve the needs of bicyclists, pedestrians and the handicapped, whether by means of constructing new facilities or by retrofitting improvements to existing structures. This report includes a review of the state of the art; a discussion of facility needs assessment procedures, including warrants and design selection criteria; the results of field evaluations of various over- and undercrossing facilities conducted by a team of engineers and a panel made up of members with various types of physical disabilities; and recommended design treatments. Also, features for non-structural solutions and innovative or less traditional treatments, as well as prototypical design strategies for both new and retrofit facilities, and examples of desirable and undesirable design practices are given.
